Mar 09 22:41:50 <ailion> Hi
Mar 09 22:42:01 <ailion> I need some help
Mar 09 22:43:40 <ailion> I'm able to build a bootable iso image for BIOS on x86 platform, the boot sector I passed as a parameter to mkisofs is "/isolinux/isolinux.bin".
Mar 09 22:45:01 <ailion> Now I'm working on a dual-socket arm64 server, which has UEFI only without legacy BIOS compatible mode supported.
Mar 09 22:46:47 <ailion> I found a document from Debian, which pass "-e boot/grub/efi.img" to mkisofs.
Mar 09 22:46:55 <ailion> https://wiki.debian.org/RepackBootableISO#arm64_release_9.4.0
Mar 09 22:47:56 <ailion> However, I can't find "boot/grub/efi.img" after installing ubuntu-18.04.4-server-arm64.iso on my working machine.
Mar 09 22:48:25 <ailion> Which package should I install to have this efi.img?
Mar 09 22:51:43 <ailion> BTW, I foud an efi.img at "debian-installer/build/tmp/cdrom_grub/grub_efi/efi.img" but I don't know if it's the corrent file since it's in a tmp dir.
